mine were pushing my bottom teeth out of alignment. also, they were putting too much pressure on my teeth and my jaws hurt a lot.

the main reason they get taken out though is because they screw up your teeth's alignment. Not everyone will get screwed up, just the ones who don't have enough space in their mouths for the extra teeth. Wisdom teeth are slowly becoming less common, as more and more people are born without them. Soon enough, humans will have evolved to have no wisdom teeth.
